Propagation Characteristics of Laguerre-Gaussian Beams with OAM in Atmospheric Turbulence

Based on Kolmogorov turbulence phase aberrations, the OAM measurement probabilities of Laguerre-Gaussian beams in atmospheric turbulence are researched. We derive the functions of OAM measurement probabilities varied with propagation distance of Laguerre-Gaussian beams. In addition, we also find that the Laguerre-Gaussian beam propagating in atmospheric turbulence will be less affected if it has smaller initial OAM topological charge.
